21379906 SP2 Volvo Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component in the pneumatic braking system of heavy commercial vehicles. It is engineered to provide consistent air pressure required for safe braking and pneumatic operations. The unit utilizes high-strength components to withstand the high-pressure environments found in heavy-duty engine systems.

Compatibility with Volvo B13R

Specifically designed for Volvo B13R trucks equipped with D13B engines, this component ensures precise air delivery. The design features a through-drive mechanism and is optimized for water-cooled operation to manage thermal loads effectively during continuous operation. It is compatible with Volvo OE requirements.

Installation and maintenance guidance

For proper installation, technicians should verify the water inlet and outlet ports (M16x1,5) and the air outlet port (M26x1,5) match the existing lines. Given the water-cooled design, ensuring clean coolant flow through the valve plate and cooling jacket is essential for maintaining optimal performance and preventing overheating in the cylinder assembly.

Selection and verification

When replacing this unit, it is vital to confirm that the displacement of 704cm³ and the ESS feature match the original equipment specifications to maintain system balance.
